Okay, that's 'heavy' explained but why should a form of music be called metal? Well, most metals are heavy, especially the metals favoured by the bands who played that genre and used metals in their names, for example Led Zeppelin, Iron Butterfly, Iron Maiden and Metallica.lack Sabbath are generally accepted to be the first heavy metal band. They were originally called Earth after J. R. R Tolkien's mythical Middle Earth. Tolkien was a local boy and is thought to have based the region of Mordor on the Black Country. All in all, it's clear where the musical form heavy metal originated.
